Selection Glitch

[PHOfficial]

I've been using UTAU for a while now, I took a break from using it and I found a glitch. I opened a .ust file, select everything to move all lyrics down an octave, but only one note moves. (A GIF of what's happening should be shown below for this) I uninstalled and reinstalled UTAU and tried it again, but the same thing happened. If anyone can help me out with this I'd appreciate it.

Click the very bottom right corner of the UTAU window to make the letter M appear. This will allow multi movement.
